Dsp-based Intelligent Anti-theft Alarm System

The technique of guarding against theft and giving an alarm is based on the means ofphysics or electronics, it will detect the inbreak in detected area automatically, alsoproduce an alarm. This's an important establishment to defend dacoity, theft, etc. Thetechnique is used widely in modern society, we may see it in home, companies, schoolsand capitals. The development and application of DSP plays an important role in it.This paper introduces the aptitude system of guard against theft and give an alarm baseon DSR This system is real-time and has a high nicety. At the same time, the alarm infocan be transmitted to the appointed cellphone in the form of SMS, so the nobody guardwill come true, it has a light future. The contents included: introducing of DSP, the basicknowledge of numerical images and the technique of motion detect of numerical images,the protocol and process of GSM. In the end, combines all parts, forms a steady-goingsystem of exact function and real-time.
